IEC 62368-1 Safety Requirements

Hazard-Based Approach

You need to understand how IEC 62368-1 changes the way you look at safety. This standard uses a hazard-based approach. You focus on finding possible dangers before they cause harm. You do not wait for accidents to happen. You look for risks in every part of your device, including wireless charging systems. You protect users from energy sources inside your products. This method helps you stay ahead of problems and keeps your devices safer.

The hazard-based approach is proactive. You identify hazards and use strategies to reduce risks. Earlier standards reacted to incidents. IEC 62368-1 helps you prevent them.

Key Compliance Tests

You must follow several steps to meet IEC 62368-1 safety requirements. These steps help you check for hazards and make sure your wireless charging devices are safe. The table below shows the main safety requirements:

Safety Requirement	Description
Identify energy sources	Recognize the energy sources within the product.
Measure energy levels	Assess the energy levels produced by the source.
Determine hazards	Evaluate if the energy produced is hazardous.
Classify energy sources	Classify the energy source into Class 1, 2, or 3.
Energy transfer	Identify how energy may be transferred into the body of product.
Safeguard schemes	Choose safeguards to protect users and reduce fire hazards.
Effectiveness of safeguards	Test safeguards under different conditions.

You use Wireless Power Test Equipment to measure energy levels and check for overheating. You log data and test safeguards to make sure they work in real-world situations.

Energy Source Classification

You must classify energy sources in your wireless charging devices. IEC 62368-1 uses three classes. Each class has its own rules for safety. The table below explains these classes:

Energy Class	Characteristics	Safeguard Requirements
Class 1	Not painful, may be detectable; ignition unlikely	No safeguard required for ordinary persons
Class 2	Painful but not injurious; ignition possible	At least one safeguard is required for ordinary persons
Class 3	Capable of causing injury; ignition likely	Multiple safeguards required; must not be accessible under a single fault condition

You check the energy class to decide how many safeguards you need. You use test equipment to make sure your device stays in the safe range. You protect users from pain, injury, and fire hazards.

Wireless Power Test Equipment for Thermal Safety

J-Type Thermocouple Technology

You need accurate temperature readings to keep wireless charging devices safe. J-Type thermocouples give you this accuracy. These sensors measure both surface and internal hotspot temperatures. You can trust the results because J-Type thermocouples have a high tolerance. The table below shows how J-Type thermocouples compare to other types:

Thermocouple Type	Standard Limits of Error	Special Limits of Error
J	±2.2°C or ±0.75%	±1.1°C or ±0.4%

KingPo’s Wireless Power Test Equipment uses J-Type thermocouples with a ±1.1°C tolerance. This means you can detect even small changes in temperature. You get reliable data for every test. This level of precision helps you meet the strict requirements of IEC 62368-1 Edition 3, CE, and UL standards.

Real-Time Temperature Monitoring

You must watch temperatures as they change during wireless charging. Real-time monitoring lets you see problems as soon as they start. KingPo’s system records data from multiple points at once. You can track both surface and hotspot temperatures. The equipment covers a wide temperature range, so you can test many types of devices.

Industry benchmarks show that response times for temperature changes range from about 1.13 to 2.63 seconds under varying loads. The table below gives you a clear view:

Load Condition	Response Time (s)	Temperature Change Response Time (s)
Varying Loads	1.56 to 2.92	1.13 to 2.63
Increased Network Load	2.3 to 6.8	N/A

Fast response times help you catch overheating before it becomes dangerous. You can use the data logging feature to create detailed reports for certification and audits. This makes it easier to prove your device meets safety standards.

Over-Temperature Protection

You need strong safeguards to prevent device failures. Over-temperature protection is a key feature in Wireless Power Test Equipment. When the system detects high heat, it can trigger alarms or stop the test. This keeps your devices and your team safe.

• Qi-certified wireless chargers slow down charging if they get too hot.

• The system uses thermal insulation to keep batteries safe from hot charging coils.

• Over-temperature protection helps you avoid fires and equipment damage.

KingPo’s equipment includes an emergency stop button. You can halt tests instantly if you see a problem. This adds another layer of safety during testing.

Tip: Always use over-temperature protection and emergency stop features during every test. These tools help you avoid costly mistakes and keep your lab safe.
